Description and Introduction

12-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 ANALOG INPUTS The TLC2543CDBRG4 is a 12-bit, switched-capacitor, successive-approximation analog-to-digital converter (ADC) manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Resolution:** 12-bit  
- **Input Channels:** 11 (multiplexed)  
- **Conversion Time:** 10 µs (max)  
- **Supply Voltage:** 4.5V to 5.5V  
- **Power Consumption:** 1.4 mW (typical)  
- **Interface:** Serial (SPI-compatible)  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** SSOP-20  

### **Descriptions & Features:**  
- **High-Speed ADC:** Provides fast 12-bit conversions with a maximum throughput of 66 kSPS.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Programmable Features:** Includes auto power-down, variable conversion speed, and unipolar/bipolar output coding.  
- **Built-in Sample-and-Hold:** Eliminates the need for an external circuit.  
- **Wide Input Range:** Supports both single-ended and differential inputs.  
- **On-Chip System Clock:** No external clock required.  

This ADC is commonly used in industrial control systems, medical instrumentation, and data acquisition applications.

Application Scenarios & Design Considerations

12-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 ANALOG INPUTS

Alternative Part Number

  • ADC128S102CIMTX/NOPB --: 12-bit 8-channel SAR ADC with SPI interface, pin-compatible family alternative to the TLC2543 12-bit 11-channel ADC, available in TSSOP.
  • MCP3208-CI/SL --: 12-bit 8-channel SPI ADC in SOIC, functionally similar successive-approximation converter suitable as a drop-in design alternative.
  • ADS7841E --: 12-bit 4-channel serial SPI ADC in SSOP, same SAR architecture and serial interface, usable when fewer channels are acceptable.
